You can create a service/time sheet from a PO. See View and Manage POs for more info.
To edit a service/time sheet, perform the following steps:
On the Service/Time Sheets page, do one of the following:
Click on its number in the Service/Time Sheets column.
Click on the Edit () icon for it in the Actions column and click on the Edit button.
Confirm or enter time against the PO line items.
You can enter only one week at a time. The week applies to all the lines.
Save or submit the service/time sheet, or add comments for your customer.
You can submit multiple service/time sheets for any amounts or quantities against one PO and against one PO line.
The service/time sheet is routed for approval to your customer.
Approval or rejection happens on the entire PO, not individual lines.
If the service/time sheet is approved, a receipt and an inventory transaction are created in Coupa for the values of each PO line and you get a notification.
If the service/time sheet is rejected, you receive a notification and you have to submit the service/time sheet again.
The type of notification depends on your notification preference settings.
